The Punch Card Mindset
“I could improve your ultimate financial welfare by giving you a ticket with only twenty slots in it so that you had twenty punches–representing all the investments that you got to make in a lifetime. And once you’d punched through the card, you couldn’t make any more investments at all. Under those rules, you’d really think carefully about what you did and you’d be forced to load up on what you’d really thought about. So you would do so much better.”- Warren Buffett
Many Buffett and Munger pupils preach following the “punch card mindset,” yet very few actually do. I really think applying this filter has made all the difference for me in my evolutionary process as an investor, and I’m quite confident it will dramatically improve your results as well; especially if you are striving to be a focused investor like Geoff and myself. What does following the punch card mindset mean to me? It means doing the due-diligence required to get to a level of certainty that you are willing to put 20%+ of your net worth in a single idea.

The best part about investing though is even if you say “no” to an idea, the amount of work you did to get to that decision can be extremely useful to you. Everything in investing is all cumulative. All knowledge stores up like compound interest. So even if you feel like you are not getting anywhere because you are not finding any actionable ideas, trust me, you are. Just keep your head down and keep chugging along.
“The most important three words in investing may be: “I don’t know.” Having strong viewpoints on a lot of securities, and acting on them, is a sure-fire way to poor returns in my opinion. In my view, it’s easier to adopt this “I don’t know” ethos by focusing on the business first and valuation second, as opposed to the other way around. I’ve found that when valuation is the overriding driver of interest, I’m prone to get involved in challenging businesses or complicated ideas and liable to confuse a …
